SPECIFICATION forming part of Letters Patent No. 268,731, dated December 5, 1882.

Application filed December 29, 1881. (No model.) Patented in England June 23, 1882, No. 2,980.

To all whom it may concern Be it known that we, JACOB RUSSELL and CHARLES BALL, both citizens of the Unitedburrs formed on their edges. They also re quire to have a chamfer, bevel, or'concave formed on their upper sides. It is to eifect these finishing operations that we have devised the machine which we will now describe.

In the drawings which serve to illustrate our invention, Figure 1 is a front elevation, and Fig. 2 is a side elevation, of the machine,

. as a whole. Fig. 3 is a plan of the bed of the machine, the frame being in horizontal section on line 3 3 in Fig. 4, Fig. 4 is a vertical lon gitudinal mid-section taken on line 4 4 in Fig. 3. Fig. 5 is a detached detail view of the upper or die roll and the bed. Fig. 6 is adetached "iew of the connecting-rod strap. Fig. 7 is a view of the face of the upper die. Fig. 8 is a detached cross-section of one of the levers for operating the lateral dies, taken on line 8 8 in 5 Fig. 4. Figs. land 2 are drawn to a smaller scale than the remaining figures.

, Let A representa substantial bed-piece, and B B substantial frames, in which the rolls are mounted. 4c 0 is a hearing-roll rotatively mounted in the frames B, and D is a traveling bed, which rests on the roll 0 and bears a die or die'plate, E.

Fis an upper roll, mounted in bearing-blocks which slide in the frames B, and are made adjustable vertically by means of screws to a.

The roll F is mounted directly over the bearing-roll by preference, and bears the upper rolling die, G.

On one projecting end of the journal of the.

roll F is fixed a large toothed wheel, H, which meshes with a pinion, I, on a driving-shaft, J, on which are mounted the usual light and loose pulleys, K. V

The bed D has a prolongation, D, which is bolted or otherwise firmly fixed to a cross head, L, which is mounted to play in crosshead guides M, which extend back of the frames B. These guides are bolted to a fixed bed, N, which is of an I shape, one end being supported on legs 0 and the other on brackets on the frame B.

On the ends of the cross-head L are wristsb b, which are coupled one to a wrist, b, on a crank, P, on the roll F, and theother to a wrist, b, on the spur-wheel H by means of connectingrods Q. Rotation of the roll F thus imparts a reciprocating motion to the bed D.

The'die E has an elevated central part, a, corresponding in shape to the inside of a horseshoe, and raised above the general level of the die a distance equal to the thickness of a shoe. When placed in the die the shoe encircles this elevated part c, the toe-calk dropping into a mortise, d, in the die, and the heelcalks dropping into recesses 01. The body of the shoe rests upon the face of the die, the heel-calks rest upon the bottom of their recesses, and the toe-calk rests upon a lifter, 0, (see Fig. 4,) with a pyramidal head which fits into the mortise d.

The upper die, G, is shaped like a horseshoe, but is a little larger than the shoe, and its center f is or may be recessed to prevent its contact with the raised center of the lower die. The rim or face f is given the proper shape or contour to impart to the upper side of the shoe the concave or bevel desired and usually found in horseshoes.

Wehave described the upper and lower dies, and will now describe the dies which have a 0 lateral movement and serve to preserve the proper curvature of the shoe while it passes between the upper and lower dies. This is accomplished by means of two dies, R It, Figs. 3 and 8,mounted on levers S S, pivoted to the 5 cross-head L at g g, and extending forward over the bed D. As the dies R and levers S are precisely alike, are operated by like means and simultaneously, it will only be necessary to describe one. The inner or operative edge, h, of the die It is as thick as the horseshoe, and is shaped to fit the outer curved edge of the same. The rear edge, h,takes under the lever S, and is secured thereto.

In order to adjust the die laterally to or from the shoe, a pair of wedges, t, is arranged between the inner edge of the lever S and shoulders h on the die, as clearly shown in Figs. 3 and 8; and in order to adjust the die lengthwise of the lever a set'screw, j, which screws "through a lug, h on thedie, is caused to bear the shoe.

against a shoulder on the lever formed by recessingthelatter. These means of setting and fixing the dies in their proper position with respect to the lever and shoe are not absolutely necessary, as the dies R might be fixed permanently to the levers S; but we prefer to secure them adjustably, as shown.

In the upper side of the lever is formed a cam-groove, 7c 70 k which is curved at its ends and straight at its middle part. The groove is engaged by-a roller, I, mounted rotatively on a bracket, 1, fixed to the frame of the machine. When the bed D (bearing the levers) is approaching the forward end of its stroke the roller Z acts upon the curved part is and throws the levers outward, so that a shoe may be properly placed on the die. On the returnstroke the roller passes into the straight middle part of the groove and throws the levers inward, pressing the die R up to and against This pressure continues until the bed approaches the backward or rear end of its stroke, when the roller engages the curved part 10 of the groove and again throws the lever out, thus releasing the shoe. At this moment the lifter e is pressed upward, and taking under the toe-calk of the shoe raises it out of the recess d in the dieE. This is accomplished by means of a cam-lever, m, which is hinged'in a groove or slot in the under side of the bed D. Thislever takes under the end of the lifter e, and when the bed moves back aswell on the under side of said lever wipes over a cam, m, fixed on the machine-frame,

v and the lifter and lever are thrown up. At the moment after the shoeis thuslifted it is brought into contact by the backward movement of the bed with a rod, a, mounted on the fixed bed N, and is thrown or knocked off the die E. This rod 11. is by preference. mounted to slide in its bearings, and a spiral spring, a, is arranged on it between the hearings in a manner to allow the rod to yield elastically if its end be pressed forcibly back. This is in order that the shoe, before it is entirely released, may be brought against the end of said rod, so as to press it back a short distance, and when the shoe is fully released the elastic force of the spring will be sufficient to drive the shoe off with considerable force.

The front ends of the levers S bear rollers 0, and these rollers rest upon bearing-springs 19, attached to the bed 1), and roll on said springs when the levers swing out and inin their clamping and releasing movements. The purpose of this construction is to raise the dies B a little bit above the bed D, normally, and maintain them in this position; but when they have grasped the shoe, and the die G is brought down upon them and the shoe they will be forced down to the bed D, the springs 19 yielding to permit this movement.

The lateral movement of the dies R is not intended to effect, ordinarily, any change in the form of the shoe. The shoe will usually be presented 'to'the machine in the proper" shape so far as its lateral curvature is concerned. Should it be improperly curved,these dies may correct the defect. Their normal funct on, however, is primarily to hold the shoe in position while the roller-die is acting on it,.

and, secondarily, to prevent the'formation of a burr on its edge'by the vertical movement of said dies, as last described. The outer periphery of the shoe, as is well known, does not present a vertical face when placed fiatwise, calks down, as on thedie E, the upper edge projecting over the lower edge.

In the ordinary mode of making horseshoes a sharp ragged burr is formed on the upper exterior angle, which must be removed before the shoe is used, and to grind this offisa costly operation. The dies R, by reason of their po sition partly above the edge of the shoe and their vertical movement as the shoe passes under the rolling die, prevents the formation of this burrentirel'y.

It is found desirable that when the die G shall have first come into contact with the shoe, as shown in Figs. 4 and 5, the bed D, bearing the shoe, should move a little faster than the periphery of the die G, in order that the metal of the shoe may be slightly drawn by said die. Therefore we provide the roll F with a long tooth or projection, q, (seen best in Fig. 5, which engages at the proper moment a shoulder, g, on the bed D, and accelerates the movement of the latter while the die G is in contact with, the shoe. As the bed moves on horizontally the tooth q passes off from the shoulder and does not again come in contact therewith until the next revolution. It is evident that this accelerated movement of the bed would be impossible without some play were allowed in the connection of the connecting'rods Q with thelnoving parts. This we provide for by making the box of the rod to play in the strap, as clearly shown at r in Fig. 6. This play or movementwill be about threefourths of an inch in a working machine.

The vertical movement of the lateral dies B may be nearly or quite equal to the thickness of the shoe-say three-eighths of an inch and we consider this movement as very important in the working of the machine. In some cases the play of these dies vertically might be entirely independent of the levers S.

The spring 12 might be replaced by other elastic means for raising the said dies R.
